  • Upgrading from 4 to 5 with UnionFS, SnapRAID and Docker

    I am planning on trying this on a cloned drive first but would like to be prepared as much as possible. After cloning I'll have the hassle of removing the system NVME drive from the underside of the motherboard to avoid any UUID conflicts. Aslo I want to avoid too much downtime as family on Covid-19 lockdown are relying on my media server (Jellyfin) to keep them entertained.


    Anyone tried this and how did it go? Any pitfalls?

  • Web GUI for docker not working

    Unsure if this relates to me accidentally upgrading php to 7.3 but now Docker GUI gives this error:


    Invalid RPC response. Please check the syslog for more information.


    And:


    Error #0:

    OMV\Rpc\Exception: Invalid RPC response. Please check the syslog for more information. in /usr/share/php/openmediavault/rpc/rpc.inc:186

    Stack trace:

    #0 /usr/share/php/openmediavault/rpc/proxy/json.inc(97): OMV\Rpc\Rpc::call('Docker', 'getContainers', Array, Array, 3)

    #1 /var/www/openmediavault/rpc.php(45): OMV\Rpc\Proxy\Json->handle()

    #2 {main}


    Syslog shows:


    Unsure where to go from here?


    Docker is working as is Portainer but I'd like to fix this if possible.


    Thanks for any help.

  • Php version for web interface

    Hi,


    I semi stuffed my system by adding a Debian non-free repo to install graphics drivers and having forgot to remove the repo before apt update/upgrade. Ended up installing stuff I didn't want but all seemed to work - until I removed an unused plugin and the web interface disappeared. Anyway fixed this by installing php7.0-xml as I found in a forum post (not OMV forum, it was down).


    I have however ended up with php v 7.3 installed - I think the default version is 7.0? All working fine now but are there likely to be problems with this and should I try to remove 7.3? Or best leave it be?

  • Upgraded: 6th HDD don't show up. Because of M.2?

    You can create a Clonezilla bootable USB drive, boot from it and image the existing M.2 to temporary storage then swap in the new NVME and write the image to this. This approach may fail if the new M.2 is smaller than the existing one. You'll find tutorials on Clonezilla easily.


    There are other approroaches but worth learning this method for future system backups etc.

  • How do you use other docker apps to use letsencrypt's certs?

    I only have experience with Apache not nginx - and not all web apps work the same way with reverse proxies.


    For Portainer see - https://portainer.readthedocs.io/en/1.10.2/faq.html - it's fussy about reverse proxies. For example trying to use the CLI for a Docker container from Portainer works from 192.168.xx.x but not from the reverse proxy address.


    For Transmission maybe use the remote GUI instead of the web address? Whcih may give the same result but worth trying.

  • Transmission download to rootfs

    It could be that the location that you usually download to has gone offline hence the rootfs filling up. Login to the system with Putty or WinSCP for example and delete or move the movies, or delete throught the Transmission UI. Once you create space reboot and the Web GUI should be available and you can fix the underlying problem.

  • How do you use other docker apps to use letsencrypt's certs?

    I had the same problems and resolved it by using a reverse proxy for emby. The advantage of this is you don't have to worry about port forwarding.


    I link to emby by https://emby.mydomian.org


    This needs you to run certbot again to create a second letsencrypt certificate for the new domain. I assume you are using nginx as web server? You'll no doubt find an example of how to do this in the emby documentation. I use Apache as my web server, I can post the necessary conf file if interested.


    Having said all this I do this on a Ubuntu 18.04 server device not OMV but the principal is the same i am sure.


    If you use for example https://mydomain.org/jackett it uses the existing certificate but


    https://jackett.mydomain.org needs a seperate certificate.

  • Monit disk error mesage

    I have a 4x4TB + 1x1TB unionfs/snapraid setup - all SATA drives on ASUS motherboard and Pentium CPU.


    This error appeared:


    Filesystem flags changed Service filesystem_srv_dev-disk-by-label-1TBHD


    Date:Sun, 29 Dec 2019 17:32:39
    Action:alert
    Host:omv
    Description: filesystem flags changed to 0x1008


    Your faithful employee,


    Monit


    Things are working as usual and short SMART test on the drive concerned did not show errors.


    Any reason for concern?

  • mergerfs not distribute data evenly

    What about using the mergerfs.balance script to even the spread of data across the drives?


    When I started with UFS/Snapraid I noticed uneven spread and this script ran for a few hours and evened disk usage up. Since then the disk use has been pretty even. My setup is MFS. This was on OMV v4.


    Naturally I had backups before I did this.

  • Expanding Snapraid

    I have 4x4TB drives using unionfs and Snapraid. If I want to add storage am I correct in thinking I'd have to buy two bigger drives as the parity drive has to be the biggest?

  • UnionFS SnapRAID 0 size files

    Thanks for the input with this, I haven't solved the problem but come up with a workaround, which it to tell Emby not to produce .nfo files and instead get Ember Media Manager (Windows) on the job to create them.


    Ember renames the empty .nfo files to .info but easy to delete these.


    Edit - just discovered tinyMediaManager - much faster at recreating the .nfo files.
